- * The viewer stream's lifetime is the intersection of their viewer connection's
- * lifetime and the duration during which at least:
- * a) their input source is still active
- * b) they still have data left to send to the client.
- *
- * This means that both the sessiond/consumerd connection or the viewer
- * connection may tear down (and unpublish) a relay_viewer_stream.
- *
- * Viewer stream updates are protected by their associated stream's lock.
